Incoming email down

Hi all - our incoming mail keeps dropping over for some reason. I cant find anything in the log files that could be the cause of this (or understand). There is a certificate error but this happens all the time. Some idiot delete a certificate now it has errors and one update re a firewall will not install. These problems occur all the time but at least twice a week the incoming mail stops. My ISP assures me that they have a relay on but when the mail drops the emails are bounced back with a delivery issue. Is it my 2008 server that is bouncing them back?
I have attached a log file and the error. I need help with the certificate as well if possible.

Please have a read of my Backpressure article and make sure you are not running low on disk space / resources as this will kill your mail stone dead as a result!

You my friend are a biscuit (Thats a good thing!!!)

Fixed the problem - the log file was staring me in the face.

Thanks for the help.

One thing though - the windows backup insists on backing up a volume and formating the external device - I have other backups on that device. Am I doing it incorrectly should I run backup exec rather?

Good news - it is a problem that is quite common and took me by surprise the first time I saw it!

I would use separate backup devices.  One for Windows Backups and one for Backup Exec (assuming you have that installed to - or for the other backups).

Windows likes it's own HDD to play with : )

You are welcome - thanks for the points.

Would have been better to accept the initial link as that is what solved your mail-flow problem - not the comment about your backups!!
